Convert Number to Day of Week

Question

I need to convert a number to a date ie

1 -> Sunday
2 -> Monday

I have the following question which aids with the opposite: day of the week to day number (Monday = 1, Tuesday = 2)

Once I am able to do this I could for example loop through and echo the day ie:

while($i < 7)
{
    echo date("N",strtotime(1));
}

Everything I am searching for seems to be people asking to convert a day to a number. Can someone please point me in the right direction

Answer 1

Just put the days in an array using the day of the week as the key. Then use date('N') to get the day of the week and use that as they key to access that array value.

$days = [
  1 => 'Sunday',
  2 => 'Monday',
  3 => 'Tuesday',
  4 => 'Wednesday',
  5 => 'Thursday',
  6 => 'Friday',
  7 => 'Saturday'
];

echo $days[date('N')];
